The South African type MY1 tender was a steam locomotive tender.
Type MY1 tenders entered service in 1952 and 1953, as tenders to the Class S2 0-8-0 shunting steam locomotives which entered service on the South African Railways in those years.
Type MY1 tenders were built in 1952 and 1953 by Friedrich Krupp AG of Essen in Germany.
The Class S2 0-8-0 steam locomotive was designed by L.C. Grubb, Chief Mechanical Engineer of the South African Railways (SAR) from 1949 to 1954, as a shunting locomotive with a light axle load for harbour work where most of the trackwork was laid with light rail. The Type MY1 entered service as tenders to these locomotives.
The tender had a coal capacity of 8 long tons (8.1 tonnes), a water capacity of 4,200 imperial gallons (19,100 litres) and a maximum axle loading of 8 long tons 18 hundredweight 2 quarters (9,068 kilograms). It was a tank wagon type tender with a cylindrical water tank, similar in appearance to the North American Vanderbilt type tender. The SAR's Types MX, MY and MY1 tenders with their cylindrical water tanks all became commonly known as Torpedo tenders.
Like the Type CL, Type MX and Type MY tenders, it rode on three-axle Buckeye bogies to reduce the axle load.
While the tender was similar in general appearance and dimensions and had the same wheelbase as the Type MY tender of the Class 24, it had a different coal bunker top design. As was done with the tenders of the Classes S and S1 shunting locomotives, the top sides of the coal bunker were scalloped out to improve the crew's rearward field of vision.
